Rube closed on 16 May 2026, so existing rube.app configurations need migration.\n\n**Merge Agent Handler.** Agent Handler's access keys can be limited to named users, tool packs and a runtime scope, with an expiry, and an agent can create an account with one documented request. No rate limit figures are published, Pro starts at $1,000 a month with no published overage rate, and failed or blocked calls spend credits.\n\n## Before you call either\n\n### Composio (API + MCP)\n\n1. Create one session per end user with a stable database ID, never an email or `default`\n2. Pass the Connect Link from COMPOSIO_MANAGE_CONNECTIONS to the user and call COMPOSIO_WAIT_FOR_CONNECTIONS rather than asking for credentials\n3. Filter the session to `readOnlyHint` tools when the task only reads\n4. Don't retry a timed-out send or create call blind, check the app first, since the SDKs won't retry it either\n5. Replace any rube.app/mcp entry with connect.composio.dev/mcp or a session MCP URL\n\n### Merge Agent Handler\n\n1. Call `search_tools` with a plain-language intent before `tools/list`. A Tool Pack can hold hundreds of tools and Slack alone lists 50\n2. Add `?connectors=slack` to the MCP URL to limit a connection to named connectors, and `?paginated=true` only if the client follows `nextCursor`\n3. Carry a user-scoped key with `runtime:all` only. The production key reaches every Registered User and the management endpoints\n4. On `reauth_required` read `data.reauth_reason`, then call `authenticate_\u003cconnector\u003e` by name. Intent search doesn't return the authenticate tools\n5. Pin `MCP-Protocol-Version` to `2025-03-26` when context is tight. Later revisions repeat object results in `structuredContent`\n\n## Questions\n\n### Which is better for AI agents, Composio (API + MCP) or Merge Agent Handler?\n\nComposio (API + MCP) scores 75.1 (BB) on agent readiness against Merge Agent Handler's 69.5 (B), and leads in 5 of 7 scored categories. Merge Agent Handler leads on security \u0026 auth and payments \u0026 pricing.\n\n### Do Composio (API + MCP) and Merge Agent Handler need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call Composio (API + MCP) and Merge Agent Handler without installing anything?\n\nYes. Composio (API + MCP) has a hosted endpoint at https://backend.composio.dev/api/v3.1 and Merge Agent Handler at https://ah-api.merge.dev/mcp.\n\n### Are Composio (API + MCP) and Merge Agent Handler open source?\n\nComposio (API + MCP) is open source (MIT).
